How to make advanced ebay search box?

I would like to make a search box on my website that searches only certain categories that I specify and displays the ebay items on my website and of course carries my affiliate id when people click on them. It would pull up results based on user entered keywords and display items within a certain mile radius. if anyone knows of such a script i would greatly appreciate it if you could point me in the right direction. i am using wordpress if that makes a difference.

Here ya go.


Here is the free version


Along with this plugin and you will have yourself a killer system.
